基　　金：陕西省农业发展办公室下达的"陕北窑洞笼养鸡技术推广"项目部分研究内容(项目编号:98-54)。

摘　　要：对引入陕北的3个商品代蛋鸡品种6个品系罗曼褐壳蛋鸡、罗曼白壳蛋鸡、海赛克斯褐壳蛋鸡、海赛克斯白亮蛋鸡、海兰褐壳蛋鸡、海兰白壳蛋鸡,在窑洞笼养条件下进行比较试验,对各品种不同品系的产蛋性能、生长发育及存活率、饲养效益进行了测定。结果 75周龄平均产蛋量分别为19.58kg、17.73kg、19.71kg、19.79kg、18.05kg和16.90kg;产蛋期料蛋比分别为2.58:1、2.45:1、2.37:1、2.48:1、2.55:1、2.47:1。饲养效益分别为18.47元/只,17.46元/只、25.45元/只、18.95元/只、16.97元/只和16.13元,研究认为海赛克斯蛋鸡的饲养效益最高,为陕北窑洞笼养鸡技术首要推广品种。Commercial breed of egg hen,such as Lohmann brown and white shell layer,Hisex brown and white shell layer,Hy-Line brown and white shell Layer,were raised in cove-coop of North shaanx-i,All strains egg-laying property,growing and developing,survival rate and raising benefit were determined. The result was as followings :the average egg production for the each strain in 75 weeks of age was respectively 19. 58 kg, 17. 73 kg,19. 71 kg,19. 79 kg,18. 05 kg and 16. 90 kg. The rate of feed consumption to egg during the egg laying was 2. 58:1,2. 45:1,2.37:1,2. 48:1,2. 55:1,2.47:1. Raising benefit was relatively 18. 47 yuan, 17. 46yuan,25. 45yuan,18. 95yuan,16. 97yuan and 16.13 yuan per hen. Based on the trials as above, the raising benefit of Hisex was the highest,so Hisex should been chosen firstly for raising egg hen technology in cave-coop of North Shaanxi.
